Abstract
The utility model relates to a camera and aims to provide a stroboscopic camera which comprises a camera CCD, an LED lamp, an LED lamp power supply, a light sensitive element, a stroboscopic control module, and an illumination intensity analyzing module is connected between the light sensitive element and the stroboscopic control module; the stroboscopic control module is connected with the LED lamp and the LED lamp power supply; the camera CCD is connected with a video signal acquisition module; the video signal acquisition module is connected with a video signal analysis module; and the video signal analysis module is connected with the stroboscopic control module. The stroboscopic camera of the utility model analyzes the illumination intensity of the camera installation position, the field synchronizing signal of the camera CCD video image signal, and the image exposure time, and then controls the LED lamp to turn on/off and the closure time and the frequency of the LED lamp. When the illumination intensity quality of the camera video image is guaranteed, electric energy is effectively saved and the service life of the camera and the LED lamp is prolonged.
Description
Technical field
The utility model relates to video camera, refers to especially a kind of stroboscopic video camera.
Background technology
Video monitoring system has spread to the application in the industry-by-industry, require part installation site dim light or rayless position according to monitoring environment, all can select the video camera with the illumination of LED lamp, cross LED lamp when low when the illumination of installation site and will be lit supplementary lighting sources as video camera, the LED lamp is lighted for a long time and can be consumed a large amount of electric energy, and can produce heat, video camera and the LED lamp life-span that operation can reduce video camera and LED lamp greatly under the environment of high temperature for a long time.Part environment for use (in tunnel, dark room) even meeting are annual all do invalid illumination, and the LED lamp of video camera is lighted for a long time like this, can reduce greatly the life-span of video camera and LED lamp.
The utility model content
The utility model proposes a kind of stroboscopic video camera, it is saves energy and the serviceable life that prolongs video camera and LED lamp effectively.
The technical solution of the utility model is achieved in that a kind of stroboscopic video camera, comprise video camera CCD, LED lamp and LED lamp power supply, it also comprises light activated element and frequent flashing control module, described light activated element and described frequent flashing control intermodule are connected with the illuminance analysis module, and described frequent flashing control module is connected with described LED lamp, LED lamp power supply respectively; Described video camera CCD is connected with the video signal collective module, and described video signal collective module is connected with the video signal analysis module, and described video signal analysis module is connected with described frequent flashing control module.
Wherein, described light activated element can carry out Real-time Collection to the illuminance of installation environment, the illuminance information that collects is transferred to the illuminance analysis module illuminance of environment is analyzed judgement, analytical information is transferred to the frequent flashing control module, whether open the LED lamp for the frequent flashing control module most important condition is provided.
Video camera CCD gathers video image, by the video signal collective module video camera CCD being collected video signal is captured in the field sync signal cycle and the image exposuring time that carry out video signal through the video signal analysis module and analyzes, produce a railway digital amount signal and transfer to the frequent flashing control mould, one road video signal is as the video signal output of video camera.
The frequent flashing control module receives the signal of illuminance analysis module and video signal analysis module simultaneously, after analysis is judged through the frequent flashing control module synthesis unlatching, shut-in time and the frequency of LED lamp are controlled, thus the function of realization LED lamp and the synchronous stroboscopic of video signal.
Provide power supply for the LED lamp after the LED lamp power supply process frequent flashing control module of the present utility model.
In sum, stroboscopic video camera of the present utility model, thereby by illuminance and the field sync signal cycle of video camera CCD video signal and unlatching, shut-in time and the frequency that image exposuring time is analyzed control LED lamp to the video camera installation site, under the prerequisite that ensures camera video image illumination quality, electric energy and the serviceable life that has prolonged video camera and LED lamp have effectively been saved.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
